Hi guys - I'm in serious need of some advice, all help greatly appreciated. Let me give you the full history.
About 3 months ago my radiator blew in my 95 j-spec TT auto. Never got to the bottom of why but replaced with a new alloy one and relocated into a dedicated oil cooler. Never had any more heat problems before or after - but when it blew the engine temp was off the scale for about 5-10mins (was stuck on motorway when it happened).
3 months on and a slow drip leak from the oil filter meant I was changed the oil last weekend. Couldn't get the filter off originally and needed it to be running, so just changed the oil n left the old filter. 3 days later and big vibrations at idle on way home from work, next morning wouldn't start. Checked and big pool of oil under the car. Replaced the filter, cleaned all the oil and chucked some new oil in... left overnight and no sign of any more leaks.
Today got mate to do a compression test. Took coil packs n sparks out and found the 6th cylinder (nearest to driver) full of water. Drained the radiator and did the compression test. Results below... also appears to now be a trace of water in the oil.
Now we (rather my mate as he's the mechanic!) think its the head gasket. I'm open to other possibilities, has anyone seen anything like this before or had a similar experience ??
Cylinder Dry Wet
1 150 170
2 150 161
3 147 163
4 150 161
5 142 161
6 Didn't try as still had some water in
(the compression meter isn't calibrated so figures may be a little off)
Any ideas ??
